Components in the rear of the enclosure
This topic describes the hardware components in the rear of the enclosure. The rear view of the Storwize® V3500 enclosure is the same whether the enclosure has 12 or 24 drive slots.
Two node canisters and two power supplies are located in each Storwize V3500 enclosure.
Node canisters might have an optional host interface adapter installed.
